For the first time, scientists have captured the exact moment DNA begins to unravel, shedding light on a fundamental chemical process that enables DNA to serve as the blueprint for life. A recent ...

This means that one strand's sugar-phosphate chain runs in ... Crick were pursuing a definitive model for the stable structure of DNA inside cell nuclei. Watson and Crick ultimately used ...

Scientists have finally captured footage of the microscopic machinery that allows our cells to copy DNA—a fundamental process ...

During cell division the two strands separate and on each strand a new "other half" is built, just like the one before. This way DNA can reproduce itself without changing its structure -- except ...

The dark bands indicate areas where the structure of the chromosome is dense ... We've now zoomed in enough to see portions of the DNA strand. The DNA is wrapped around histones -- protein ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single ... The double helix unwinds, and each strand serves as a ...

In eukaryotes, DNA is tightly wound into a complex called chromatin. Thanks to the process of chromatin remodeling, this complex can be "opened" so that specific genes are expressed. Various ...

a similar approach to making biosensors was developed using a single DNA strand rather than a DNA origami structure. That earlier work was led by Kevin W. Plaxco (PhD '94) of UC Santa Barbara ...

A new structural blueprint paves the way for improved targeting of cancer cells, particularly those with BRCA1 and BRCA2 ...

the AMP is transferred to the 5’-end of the 5’-phosphate-terminated DNA strand to form DNA-adenylate — an inverted pyrophosphate bridge structure, AppN. In this reaction, the 5’-phosphate oxygen of ...
